Hello,

It may be not the Apigility error.

As you have not specified the OS I do assume that you use some Unix based system.

Sometimes I do experience similar problem [with Linux] and every time it happens because of the project files` permissions.

It happens often when I do composer update with IDE or with CLI as my primary username. In such a situation apigility as www-data:www-data as no permissions to operate on config files.

I hope it will help others.
